More than 40,000 new property millionaires have been created across Britain this year so far amid rising house prices, according to a website.

In total, some 660,900 homes across the country are now estimated to be worth at least £1 million - an increase of more than 40,800 since January - Zoopla found.

Four out of five (82%) of Britain's property millionaires live in London (60%) or the South East (22%) of England.

Nestled in the W8 postcode of London, Kensington Palace Gardens, with its imposing mansions, was identified as Britain's most expensive street. An average home in the road, which has previously been nicknamed "the boulevard of billionaires," will set a buyer back £38.26 million.

The Boltons, in the SW10 postcode was found to be the second most expensive street with a home worth £33.31 million typically.

Across Britain, there are now 12,418 streets where the average property value is more than £1 million, according to Zoopla's calculations.

Outside London, the most expensive postcode is in Virginia Water in Surrey (GU25), where the average home costs more than £1.3 million.

Many of Britain's million-pound properties are clustered around the South East commuter belt. Some 184 streets in Guildford, Surrey, have average house prices of more than £1 million.

Zoopla spokesman Lawrence Hall said: "Whilst London will always attract buyers for trophy homes from across the globe, those looking for million pound-plus homes should also consider areas outside the capital that make the list such as Guildford, Sevenoaks or Esher, where they will get more bang for their buck."
